The Sun, The Genome, and The Internet: Tools of Scientific Revolution (New York Public Library Lectures in Humanities)

One fashionable school of thought holds that scientific revolutions are spurred primarily by shifts in the basic concepts that science understands the world with, and that those shifts are largely the outcome of struggles in the social and political realms. Freeman Dyson, however, is having none of it. For him, scientific breakthroughs owe just as much to the introduction of new technologies--the telescope in early modern Europe, for instance; the computer more recently. He's not the first to make that argument, but his lifetime of accomplishments as an eminent theoretical physicist puts some heft behind his claims.

Dyson likewise argues that new technologies can have as much of an effect on the social and political realms as new ideologies do. In particular, he cites three burgeoning technologies--solar energy, genetic engineering, and the Internet--for their potential to affect a more equitable worldwide distribution of wealth and power in the coming century. His visions of the future meander a bit, and they include such seemingly outlandish possibilities as forests of genetically enhanced trees oozing high-octane fuel from their roots and laser-launched earthlings colonizing the comets of the Kuiper Belt. But it's the business of visionaries to be outlandish, after all, and you have to admit: this one does have better credentials than most. --Julian Dibbell
